1. N FCC Numbering Symposium State of the NANP Presented by the North American Numbering Plan Administrator (NANPA) and the National Pooling Administrator (PA) John Manning – Amy Putnam November 4, 2004

2. 2 Outline NANP Past and Present –Review of NPA/CO code assignment history NANP Resource Administration –Number assignment policies and practices –1K block pooling implementation Looking Forward at NANP Exhaust –Drivers of NANP exhaust

3. 3 NANP in 2000 Area Code Exhaust –25 new NPAs assigned –14 NPAs placed into service –68 NPAs in jeopardy of exhaust –37 new NPA relief projects implemented by NANPA Central Office Code Assignments –Total of 15,400 central office code assigned –Average of 1,280 codes assigned per month NANP Exhaust –Projected as soon as 2012 or with the implementation of national number pooling 2015 – 2025

4. 4 NANP in 2000 (cont) FCC Number Resource Optimization Efforts Initiated –Number optimization requirements Requirements for resource assignment –Proof of authority and network readiness for initial resources –Month-to-Exhaust criteria and utilization thresholds –NRUF on file –Individual number administration requirements Semi-annual reporting of utilization and forecast data (NRUF) Scheduled rollout of mandatory 1K block pooling New reclamation process State role in assignment process –Safety valve process, access to CO code application/information

5. 5 NANP in 2002 Area Code Exhaust –3 new NPAs assigned –9 NPAs placed into service –41 NPAs in jeopardy of exhaust –2 new NPA relief projects implemented by NANPA Central Office Code Assignments –Total of 7,200 central office code assigned –Average of 600 codes assigned per month NANP Exhaust –Projected 2031 - 2035

6. 6 NANP in 2004 Area Code Exhaust –4 new NPAs assigned over last two years; one NPA returned –1 NPA placed into service –Fewer than 40 NPAs in jeopardy of exhaust –Only 1 new NPA relief project implemented by NANPA in two years Central Office Code Assignments –Yearly assignment rate of 3,000 central office codes –Average of 250 codes assigned per month NANP Exhaust –April 2004 - Projected beyond 2035

7. 7 NANP Resource Administration Eligibility for Resource Assignment –Regulatory directives and industry guidelines identify who is eligible to receive NANP resources –Most common entities receiving geographic NPA resources include ILECs, CLECs, wireless entities and paging providers Applicant must demonstrate it is: –authorized to provides service in the area for which the numbering resources are requested and –capable of providing service within 60 days of resource activation –These requirements pertain to both central office codes (10,000 numbers) and pooled blocks (1,000 numbers) available via the National Pooling Administrator (PA)

8. 8 NANP Resource Administration Applying for Number Resources –All applications for numbering resources (i.e., CO codes or blocks) in mandatory pooling rate centers must be submitted to the PA –For optional pooling rate centers, participating service providers submit their request for blocks to the PA while non-participating carriers go directly to NANPA for CO codes –For rate centers excluded from pooling, all requests go directly to NANPA

9. 9 NANP Resource Administration Thousands Block Pooling Implementation in U.S. –State Trials First was Illinois 847 implemented June 1, 1998 Between June 1998 and March 2002, state trial pools were implemented in 27 states and over 100 NPAs National Pooling Administration System (PAS) rolled out on March 15, 2002 –There are 20,584 rate centers in U.S. NPAs, of which: 7,372 have mandatory number pooling –5,766 inside Top 100 MSAs –1,606 not in Top 100 MSAs but mandatory as a result of state pooling trials 903 have mandatory pooling with only a single service provider 5,861 have optional pooling rate centers 6,448 are excluded from pooling –Pools have been opened in all 272 U.S. NPAs 266 NPAs have assigned blocks NPAs without assigned blocks: MA 351, GA 470, PA 878, AK 907, PR 939, MI 947

10. 10 NANP Resource Administration Number of CO Codes Opened to Replenish Pools –2,890 Number of CO Codes Saved as a Result of 1K Block Number Pooling –12,617 Number of Assigned Blocks in PAS

11. 11 NANP Resource Administration

12. 12 Current Status of the NANP Number optimization measures have proved successful –Delay in both NPA and NANP exhaust Demand shifted from codes to blocks –Increasing block assignments –Better positioned to absorb changes in the marketplace and associated demand impacts Increased awareness of number usage –NRUF reporting

13. 13 Looking Forward at NANP Exhaust Potential drivers of NANP exhaust: –Introduction of new technology/services/players Changes in eligibility requirements Participation in current optimization efforts LRN requirements Use of numbers –Number optimization efforts Further deployment of existing optimization measures Implementation of other optimization measures to increase utilization of existing resources
